He cleared the centre of the room; stooped and drew a circle of red on the floor, around the spot where he stood; wrote in the four quarters mystical signs, and numbers which were all powers of seven or nine; examined the whole ring carefully, to see that no smallest break had occurred in the circumference; and then rose from his bending posture. As he rose, the church clock struck seven; and, just as she had appeared the first time, reluctant, slow, and stately, glided in the lady. Cosmo trembled; and when, turning, she revealed a countenance worn and wan, as with sickness or inward trouble, he grew faint, and felt as if he dared not proceed. But as he gazed on the face and form, which now possessed his whole soul, to the exclusion of all other joys and griefs, the longing to speak to her, to know that she heard him, to hear from her one word in return, became so unendurable, that he suddenly and hastily resumed his preparations. Stepping carefully from the circle, he put a small brazier into its centre. He then set fire to its contents of charcoal, and while it burned up, opened his window and seated himself, waiting, beside it. It was a sultry evening. The air was full of thunder. A sense of luxurious depression filled the brain. The sky seemed to have grown heavy, and to compress the air beneath it. A kind of purplish tinge pervaded the atmosphere, and through the open window came the scents of the distant fields, which all the vapours of the city could not quench. Soon the charcoal glowed. Cosmo sprinkled upon it the incense and other substances which he had compounded, and, stepping within the circle, turned his face from the brazier and towards the mirror. Then, fixing his eyes upon the face of the lady, he began with a trembling voice to repeat a powerful incantation. He had not gone far, before the lady grew pale; and then, like a returning wave, the blood washed all its banks with its crimson tide, and she hid her face in her hands. Then he passed to a conjuration stronger yet.
